  mjseim. 
  

  

  I 
  have 
  more 
  tban 
  ouce 
  killed 
  individuals 
  of 
  both 
  at 
  a 
  single 
  shot, 
  in 
  

   trees 
  of 
  considerable 
  height. 
  

  

  Apropos 
  of 
  MegnJurns 
  palnsffis 
  and 
  }[. 
  rutieeps, 
  tlie 
  ranges 
  of 
  the 
  two 
  

   species 
  overlap 
  not 
  in 
  Marinducjue 
  alone, 
  but 
  in 
  Mindoro, 
  Luzon, 
  and 
  

   Saniar. 
  I 
  am 
  unable 
  to 
  agree 
  with 
  Steere's 
  statement 
  that 
  there 
  is 
  a 
  

   sharp 
  distinction 
  of 
  habitat 
  here, 
  M. 
  riificeps 
  being 
  found 
  in 
  waste 
  

   places 
  inland, 
  which 
  had 
  grown 
  u]) 
  to 
  high, 
  coarse 
  grass, 
  while 
  M.palns- 
  

   triti 
  was 
  found 
  close 
  aU)ng 
  the 
  beach 
  in 
  open 
  grassy 
  i)laces. 
  The 
  two 
  

   species 
  are 
  certainly 
  to 
  bo 
  found 
  side 
  by 
  side 
  in 
  the 
  sann^ 
  fields, 
  although 
  

   21. 
  palustrifi 
  is 
  the 
  bolder 
  of 
  the 
  two, 
  and 
  hence 
  moje 
  likely 
  to 
  be 
  

   collected. 
  

  

  In 
  estimating 
  the 
  value 
  of 
  observations 
  on 
  habits 
  the 
  "personal 
  

   equation" 
  must, 
  of 
  course, 
  be 
  taken 
  into 
  account. 
  I 
  can 
  only 
  say 
  that 
  

   the 
  above 
  statements 
  are 
  based 
  on 
  nearly 
  three 
  years 
  and 
  a 
  half 
  of 
  

   actual 
  field 
  work 
  in 
  the 
  Philippines, 
  and 
  that 
  I 
  believe 
  they 
  will 
  be 
  

   found 
  to 
  be 
  correct 
  so 
  far 
  as 
  they 
  go. 
  

  

  In 
  speaking 
  of 
  the 
  general 
  distribution 
  of 
  the 
  genera 
  represented 
  by 
  

   two 
  or 
  more 
  species 
  in 
  one 
  or 
  more 
  of 
  the 
  islands, 
  Steere 
  states 
  that 
  

   "whenever 
  the 
  birds 
  of 
  the 
  two 
  sections 
  of 
  one 
  of 
  the 
  genera 
  named 
  

   above 
  differ 
  greatly 
  in 
  size, 
  the 
  species 
  of 
  the 
  section 
  of 
  larger 
  longer- 
  

   winged 
  birds 
  will 
  be 
  more 
  widely 
  distributed 
  than 
  the 
  smaller 
  birds 
  of 
  

   the 
  other.'' 
  His 
  first 
  illustration 
  of 
  this 
  rule, 
  Xinox 
  IngKbris. 
  is 
  certainly 
  

   well 
  chosen. 
  His 
  second, 
  Fhabotreron 
  amethystina, 
  is 
  unfortunate. 
  He 
  

   says 
  that 
  it 
  apparently 
  extends 
  over 
  the 
  areas 
  of 
  the 
  five 
  smaller 
  spe- 
  

   cies. 
  In 
  reality 
  it 
  is 
  confined 
  to 
  the 
  eastern 
  Philippines 
  (Luzon 
  to 
  

   Mindanao), 
  and 
  its 
  place 
  is 
  occupied 
  elsewhere 
  by 
  F. 
  macnlipectus^ 
  /'. 
  

   frontdli.s, 
  I\ 
  ci)iereiceps, 
  and 
  P. 
  brunneieeps, 
  species 
  which 
  had 
  not 
  been 
  

   described 
  at 
  the 
  time 
  he 
  wrote. 
  

  

  Dicacum 
  pijgmncum 
  is 
  the 
  most 
  widely 
  distributed 
  Philippine 
  repre- 
  

   sentative 
  of 
  its 
  genus, 
  overlapping 
  the 
  ranges 
  of 
  four 
  other 
  species, 
  

   yet 
  is 
  the 
  smallest 
  of 
  the 
  Philippine 
  Dicaeidae. 
  

  

  I 
  con(!lude, 
  therefore, 
  that 
  the 
  rule 
  of 
  distribution 
  above 
  (fuoted 
  does 
  

   not 
  invariably 
  hold, 
  and 
  that 
  other 
  factors 
  than 
  size 
  and 
  length 
  of 
  

   wing 
  play 
  a 
  ])art 
  in 
  determining 
  whether 
  the 
  range 
  of 
  a 
  species 
  shall 
  

   be 
  wide 
  or 
  restricted. 
  

  

  Steere's 
  next 
  and 
  final 
  list 
  (List 
  E) 
  includes 
  five 
  genera 
  with 
  ten 
  

   sjjecies, 
  in 
  Avhich 
  two 
  species 
  of 
  the 
  same 
  genus 
  were 
  found 
  existing 
  

   together 
  in 
  the 
  same 
  islands, 
  these 
  not 
  appearing 
  to 
  him 
  to 
  differ 
  

   enough 
  to 
  warrant 
  i)lacing 
  tiiem 
  in 
  different 
  sections 
  of 
  the 
  genus. 
  In 
  

   this 
  list 
  he 
  placed 
  }feliniopitta 
  {PiWt), 
  Crm'ujer^ 
  Megalurus^ 
  Cistieolo, 
  

   and 
  Tanygnathiis, 
  each 
  of 
  these 
  genera 
  being 
  credited 
  with 
  two 
  species.

  find 
  it 
  difficult 
  to 
  understand 
  why, 
  having 
  swallowed 
  the 
  camel, 
  he 
  

   should 
  have 
  difficulty 
  with 
  the 
  tail. 
  The 
  differences 
  between 
  the 
  two 
  

   species 
  of 
  Pitta 
  with 
  which 
  he 
  begins 
  this 
  list 
  are 
  very 
  decided, 
  and 
  if 
  

   Dicacum 
  everetti 
  and 
  /). 
  hypolencum 
  are 
  to 
  be 
  placed 
  in 
  List 
  D 
  and 
  

   referred 
  to 
  different 
  subgenera, 
  why 
  not 
  these 
  two 
  species 
  also 
  ?
